Otherwise, garbage will\nleak from the stack to the firmware (when ssid is less than 32 bytes\nand/or when params->pmkid is set). Then, pass the params->pmkid to the\nfirmware (without it, the firmware caches a garbage PMKID on successful\nauthentication and denies a subsequent association request that includes\nthe PMKID).","state":0,"publishedAt":"2026-10-06T08:46:38.525+00:00","modifiedAt":"2026-10-19T09:18:01.119+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/wireless/broadcom/brcm80211/brcmfmac/cyw/core.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"66f909308a7c05082919ff214a0bbe2a76aa0283\",\n                            \"lessThan\": \"c2cf589c7d546557ed60c43f2ec014279265dfbf\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"66f909308a7c05082919ff214a0bbe2a76aa0283\",\n                            \"lessThan\": \"6fba6233e9ca7718661e53555a3961c58772c21a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"66f909308a7c05082919ff214a0bbe2a76aa0283\",\n                            \"lessThan\": \"e2de8d5eb2984416affdd9559e55f37c7f1bbf47\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/wireless/broadcom/brcm80211/brcmfmac/cyw/core.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.54\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.8\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/c2cf589c7d546557ed60c43f2ec014279265dfbf","https://git.kernel.org/stable/c/6fba6233e9ca7718661e53555a3961c58772c21a","https://git.kernel.org/stable/c/e2de8d5eb2984416affdd9559e55f37c7f1bbf47"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98350","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98350","identifiers":["CVE-2026-98350"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
